Each tool is built to the needs and requirements of the customer. Typical variables to consider: Counterbore (ØD) to hole (Ød) ratio (Max 2x hole diameter minus 1mm (0.040”)), in process hole diameter and tolerance, over all tool length, interrupted cut or weldments, material quality, machine or part rigidity, surface finish, cast surfaces or machined surface. Tooling options may include manual or automated tool changer (ARD) arm, guide & wear bushings, and front & back cutters. Please note large ratios and difficult applications require a single blade or cartridge cutter for added stability. The tool head is modified to accommodate the single blade application (GH-E). (Max ratio = Ød x 2 - 1mm) |
